Nuclear matter has finite baryon number density, finite (negative) isospin density and, under certain conditions, finite (negative) strangeness density. Since having a finite chemical potential for baryon number makes the fermion determinant complex and simulations intractable, we restrict ourselves to zero baryon-number chemical potential. QCD at finite chemical potential μI for isospin (I3) a...

the paper is devoted to solution of some problems in nuclear power station generating unit intellectual control systems using genetic algorithms on the basis of control system model development, optimizations methods of their direct quality indices and improved integral quadratic estimates. some mathematical vector models were obtained for control system multicriterion quality indices with due ...

Nuclear magnetic shielding tensors computed by the gauge including atomic orbital ~GIAO! method in the Hartree–Fock self-consistent-field ~HF-SCF! framework are partitioned into magnetic contributions from chemical bonds and lone pairs by means of natural chemical shielding ~NCS! analysis, an extension of natural bond orbital ~NBO! analysis. NCS analysis complements the description provided by ...

in this scientific research, mno2 nanoparticles (nps) have been successfully prepared by a precipitation method using kmno4, mnso4.h2o and h2o2 (30%) as the precursors. as-prepared sample was identified by x-ray diffraction (xrd), scanning electron microscopy (sem), transmission electron microscopy (tem) and infrared (ir) techniques. the transmission electron microscopy (tem) showed 7-8 nm rang...

bcn compounds have been researched theoretically and experimentally widely. in this paper, weintroduce the theoretical prediction of ternary b-c-n compounds. nmr spectroscopy was employedextensively to study these ternary nanostructures. we discuss the utilization of chemical shiftinformation as well as ab initio calculations of nuclear shielding for h20134c9n4 structuredetermination. we calcul...

Abstract The Fukushima Daiichi accident generated degraded nuclear fuel material, mixed with other reactor components, known as molten core-concrete interaction (MCCI) material. Simulant MCCI material was synthesised, excluding highly radioactive fission products, containing depleted U, and incorporating Ce a surrogate for Pu. Multi-modal µ-focus X-ray analysis revealed the presence of expected...

Alterations in nuclear morphology are closely associated with essential cell functions, such as cell motility and polarization, and correlate with a wide range of human diseases, including cancer, muscular dystrophy, dilated cardiomyopathy and progeria. However, the mechanics and forces that shape the nucleus are not well understood. Here, we demonstrate that when an adherent cell is detached f...

chemical hardness (), absolute electronegativity (), and electrophilicity () have importantapplications in inorganic chemistry. these concepts are defined quantitatively as � � �� � ����,� � �� � ����, � � ������where i is the ionization energy and a is the electron affinity. in thisstudy, graphical method was used to see the relation of electron configuration with chemicalhardness, absolute...

The nuclear envelope (NE) is a double membrane system that is both a part of the endoplasmic reticulum and part of the nucleus. As its constituent proteins tend to be highly complexed with nuclear and cytoplasmic components, it is notoriously difficult to purify. Two methods can reduce this difficulty for the identification of nuclear membrane proteins: comparison to contaminating membranes and...

Berberis vulgaris L (B. vulgaris) and its main constituent berberine have been used in traditional medicine for a long time. This medicinal plant and berberine have many properties that have attracted the attention of researchers over the time. According to several studies, B. vulgaris and berberine exhibited anti-inflammatory, antioxidant, anticonvulsant, antidepressant, anti-Alzheimer, anti-c...
